Question Why not a ribbon tweeter instead of a horn tweeter?

I was thinking about adding the Fostex T90A to my Sachiko/Fostex 208 Sigma build, but now I am rethinking that to use a ribbon tweeter instead. I really can not see a down side to this, but maybe I am overlooking something. If I am please inform me before I start this build :-)
The Fountek NeoCd2.0M, a 5" ribbon tweeter which is 98 db efficient. This should be fine with minimal need to damp the tweeter to match the Sigma 208. What do you all think about this?

Looks like we're searching for the same answer.
I like the sound of ribbons but the set back that
I've notice is low dispersion characteristics.

The dispersion aspect does not bother me. I have owned ribbon speakers in the past and do not mind a sweet spot to deal with. I am usually always seated when I am seriously listening anyway :-)

Hi Micheal,

I know what you mean. Yes aside from horn tweeters which I have no experience, ribbons sounds the most realistic to me.
Always very sweet & clear without sounding hi-fi. Considering
the Fountek's surface area, the sound could be overpowering
when used in conjuntion with your Sigma's. Might drown out the
lows.

Default I don't think that will be an issue with drowning out the lows.

I will be crossing over at a very high frequency (approx. 10K) so I do not feel that will be an issue. The extra surface area will hopely just lower the distortion.

Ribbons are often used (Basszilla for instance).

The downside of a ribbon is that its dispersion is wider than a typical horn, so there is more of a dispersion flare at the XO.

That said when i use a supertweeter on my FonkenPrimes, half the time it is a set of CSS Ribbons (Aurum Cantus) or a set of Foster horns.

For use as a supertweeter a shorter ribbon will be better.

Default Why is that Dave?

What does the shorter ribbon gain you? The frequency length does get shorter as frequency increases, but is it really that important at these frequencies?

The taller the ribbon, the poorer the vertical dispersion, a uniform dispersion will have a better match to the FR. Also a longer ribbon is usually a trade-off between HF for LF to enable a lower XO.
